integrity means which doesn't allow duplication of files.

we have 3 types of integrity rules.
  
     1. Entity Integrity Rule :   In this Primary key can't 

be null.

     2. Referential Integrity :   It tells the relation 

between the Master Table and Child table.

     3. Business Rule Integrity.

TKPROf is one of the most useful utilities available to 
DBAs for diagnosing performance issues.  It essentially 
formats a trace file into a more readable format for 
performance analysis.  The DBA can then identify and 
resolve performance issues such as poor SQL, indexing, and 
wait events.

we have to check all the contents in the form ,and see that 
no feild is beyond its frame.

we have to check all the contents in the form ,and have to 
check that no feild is beyond its frame is left.

If we want to make any adjustments in the layout regarding 
the items in that layout ,then we have to set the flex mode

Suppose we want to extand the repeating frame, in that case 
we use flex mode . If we will not use flex mode It will not 
move.

There are 2 modes in Layout Editor .
They are 1) Confine Mode 2) Flex Mode
1) Confine Mode :- If the Confine Mode is ON then the 
repeating frame can not be moved.
If the Confine Mode is OFF then the repeating frame can be 
moved outside the frame.

2) Flex Mode :- If the Flex Mode is ON then the repeating 
frame can be moved out.
If the Flex Mode is OFF then the repeating frame can not be 
moved outside the frame.

1)Confine mode:

Paper Layout view mode that prevents child objects from 
being moved or resized on or outside their parent objects


2)Flex mode:

 Paper Layout view mode that automatically resizes or 
shrinks parent objects when child objects are moved or 
resized, 
  and adjusts the positions of other layout objects that 
might otherwise be affected by the repositioning or 
resizing of
 the objects.
